Morphology
The noun is composed of the adjective 'upper' (at the top) plus 'cannon' understood here as an armour plate for the arm, so the phrase directly denotes the upper part of that plate. This is a straightforward adjective+noun composition following common English patterns, making the meaning predictable to a B1 learner who knows both constituents (noting only a potential ambiguity with the more common sense of 'cannon' as artillery).
Etymology
Upper cannon may come from old armor where the part called cannon looked like a short metal tube, and upper shows it sat on the 'upper part of the arm'. That's why the term means the plate that covers that part of the arm.
